@rimbu/common

This package exports common types and objects used in many other Rimbu packages.

Here is a brief overview:

Name	Description
CollectFun	types and values used in various collect methods in the collection.
Comp	an interface and default implementations of comparison functions to order/sort values.
Eq	an interface and default implementations of equality functions to check value equality
Err	functions to easily create error throwing behavior as fallback values
FastIterable	an Iterable implementation that can be more performant than usual iterables
IndexRange	utilities to select index ranges in indexed collections
OptLazy	a utility to provide values that can optionally be lazy
Range	utility types to specify ranges for comparable types
Reducer	an API to create reusable pieces of logic that process streams of data that can be processed in parallel
TraverseState	a utility for loops to maintain the traversal state
Update	a standard way to update a value

Other than these values, there are a number of utility types that are exported that are also used throughout the collection.

Installation

All types are exported through @rimbu/core. It is recommended to use that package.

To install this package separately:

Yarn/NPM

yarn add @rimbu/common

or

npm i @rimbu/common

Deno

Create a file called rimbu.ts and add the following:

export * from 'https://deno.land/x/rimbu/common/mod.ts';

Or using a pinned version (x.y.z):

export * from 'https://deno.land/x/rimbu/common@x.y.z/mod.ts';

Then import what you need from rimbu.ts:

import { Eq } from './rimbu.ts';

Because Rimbu uses complex types, it's recommended to use the --no-check flag (your editor should already have checked your code) and to specify a tsconfig.json file with the settings described below.

Running your script then becomes:

deno run --no-check --config tsconfig.json <your-script>.ts

Recommended tsconfig.json settings

Rimbu uses advanced and recursive typing, potentially making the TypeScript compiler quite slow in some cases, or causing infinite recursion. It is recommended to set the following values in the tsconfig.json file of your project:

{
  "compilerOptions": {
    "skipLibCheck": true,
    "noStrictGenericChecks": true
  }
}

Usage

import { Eq } from '@rimbu/common';

console.log(Eq.stringCaseInsentitive()('abc', 'AbC'));
// => true
